Federal (USPTO) — start here
A federal registration, filed once through the USPTO, gives nationwide rights that include Delaware. It’s the right starting point for almost any business selling across state lines, online, or planning to expand beyond Delaware.
Delaware state registration
Delaware’s state trademark register is run by the Division of Corporations (Secretary of State). The published filing fee is $150 ($100 application + $50 certificate), with registrations renewing every 10 years. It only protects a mark within Delaware’s borders, not nationwide — always confirm the current process and fee on the agency’s own page before filing.
When does a Delaware state trademark make sense?
- Your business genuinely operates only within Delaware — a local shop, restaurant or service business with no plans to sell out of state or online.
- You want fast, low-cost protection now while a federal intent-to-use application is still pending.
- You need to establish Delaware-specific priority for a name ahead of local competitors.
For most brands — especially anything sold online, as software, or shipped across state lines — federal registration is the stronger, more durable choice, and a Delaware filing (if used at all) is a complement to it rather than a substitute.
